Can only a portion of a longer document like a thesis or dissertation be edited?

Of course, but not advisable. Experience has shown that consistency of style is seldom achieved with only a partial edit.

  • A complete edit is what could make the difference between an acceptable paper (or not) and an excellent paper.
  • Also, certain important formatting crosschecks and content consistency items cannot be implemented by the editor if the whole document is not paid for. But of course, the choice is always the students.
